Our knowledge of the high-energy universe is undergoing a period of rapid change as new astronomical detectors of high-energy radiation start to operate at their design sensitivities. Now is a boomtime for highenergy astrophysics, with new discoveries from Swift and HESS, results from MAGIC and VERITAS starting to be reported, the upcoming launches of the γ-ray space telescopes GLAST and AGILE,...

In the recent years, interstitial brachytherapy implantation has become the treatment of choice for early stage prostate cancer patients. Treatment of prostate cancer with radiation is traced back to 1909. Originally this treatment modality was very crude and could not gain much popularity till 1982. Advancements in radioactive source designs, introduction of new low energy radioactive sources,...

Random walk on a graph is a Markov chain and thus is ‘memoryless’ as the next node to visit depends only on the current node and not on the sequence of events that preceded it. With these properties, random walk and its many variations have been used in network routing to ‘randomize’ the traffic pattern and hide the location of the data sources. In this paper we show a myth in common understand...

The process of globalization, accelerated industrial development, continuous technological advancements, and the ever-growing global population are factors that contribute to increased utilization existing energy sources. However, fossil sources limited inadequate in face these developments. Consequently, countries have started seeking alternative sources, leading renewable This research aims h...

The achievement of technologically efficient solutions for energy generation, distribution and usage represents a crucial need of modern society, both for environmental and economic reasons. An important role in tackling future energy challenges is played on one hand by the replacement of the electrical energy production from conventional fossil based (coal, natural gas, and oil) sources to ren...
